The character is listed simply as “Cora” in all official source material.
She is Derek Hale's younger sister and a werewolf. She survived the fire without Derek Laura or Peter knowing that she did. In Riddled, it's revealed that she was in South America during her six year absence. She only returned to Beacon Hills after she heard of a powerful Alpha who was a member of The Hale Family.
Upon her return, however, Cora was taken captive by The Alpha Pack along with Erica and Boyd and starved of moonlight for three months which makes her lose control. After Derek discovers her, he takes her in and she helps in attempting to take down Deucalion.
After surviving being poisoned by a Darach and the Alphas are defeated, she and Derek leave Beacon Hills and he sends her back to South America for her own safety.
Cora was held prisoner in a bank vault lined with Hecatolite. When once again exposed to the power of the moon, she turned wild and was out of control and fights Derek and Scott McCall before escaping. (Read More...)
